lIMPROVEMENT IN' COCKLE-SEPARATING- MACHINES.

Specifica-tion forming part ofLetters. Patent No.9p2,073 dated June 29, 1869.

To all lwhom it may concern Be it known that I, FREDERICK W. MAsE, ot' the village of Waukau, in the county of Winnebago and State of Wisconsin, have invented a new and Improved Machine for Separating Gockle and other Foreign Substance from Wheat and other Grains; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,.mak'ing a part ot' this specification.

' The nature of my invention consists in the use of a revolving hollow cylinder set slightly on an incline, with the inside periphery or surface covered with indentations or cavities, each of which are of a proper form and size to receive foreign matter equal or less in size than a cockle-seed, but not of sufficient size to receivev the grain. The cavities may also be increased in size and used to separate mixed grain. A dishin g scoop-shaped receiver is placed inside the cylinder, resting on proper bearings, and

receives a shaking or vibratory motion with the revolving of the cylinder. The grain is placed in a hopper and through a conductor is received into the bottom of the cylinder. As the cylinder revolves, the foreign substance is deposited in the cavities on the inside of the cylinder, and when carried up to a proper angle is emptied into the vibratory receptacle. The grain passes out of the cylinder into one conductor, and the cockle passes out of the scoop-shaped receptacle into another conductor, and thus the cockle and foreign subtance are entirely separated from the grain.

Figure l is a longitudinal section in a Vertical plane. Fig. 2 is a cross-section cutting through dotted line .fr x. Fig. 3 is a perspective view of the cylinder B, with an opening showing cavities 3 on inside surface. Fig. 4 is a perspective view of a scoop-shaped cockle= receiver.

A A A is a rectangular frame. B is a hollow cylinder, provided with collars 2 2 and bearings Nb. C is a cockle-receiver. D is a hopper. d is a conductor from hopper to cylinder B. E E is a frame-work that supports the cockle-receiver, with bearings at El El. g is a gear-wheel. g is a pinion on shaft M. M M are bearings of shaft M. N is a pulley where power is applied by belt, crank, or otherwise. his a bevel-gear. t' is a bevelpinion on a shaft that has-bearings in ft2. k is a crank. lis a connection between crank y k and cocklereceiver at E2.

I will now proceed to describe the operation of my machine: Power being applied at N on shaft M, a revolving motion is communicated tothe cylinder B through the pinion g and gear-wheel g. From the shaft M a vibratory.

motion is also communicated to the cockle-re ceiver C through the bevel gear and pinion It cast into the cockle-receiver G. The grain passes out of the cylinder B into the conductorp, and the foreign substance separated from the grain passes from the cockle-receiver into the conductor o.

In using my machine for separating mixed grains, as the separating of wheat from oats, the wheat would be cast into the cavities and received into what is herein designated as a cockle-receiver, and the oats and foreign substance wll be discharged at the outer endv of the cylinder.

So far as relates to the cavities or cells, my invention consists in their arrangement on the inner periphery of a cylinder in contradistinction to their arrangement on the exterior surface of a moving body, whether the same be cylindrical or plane.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A revolving cylinder, B, with the inner periphery provided with cavities 3, substantially as described, for the purposes set forth.

2. The cylinder B, provided with cavities', in combination with vibratory receiver C and hopper D, substantially as described, for the purposes set forth.

3. The cylinder B, when provided with collars 2 2, bearings b b', and gear-"wheel g, as and for the purposes Aset forth.

4. The shaft M, provided with a driving pulley or crank at N, pinion g', bevel-gear wheel h, bevel pinion and shaft t', crank k, connection l, when used in combination with and for operating cylinder B and receiver C, subtantially as described, for the purposes set orth.
